Based on a random sample of 60 of a particular model of used cars, the following model was estimated: y=Bo+le+8 Where y is the selling price (in thousands of E's) and x is the mileage (in thousands of miles). Least-squares estimates are provided in the table below: Estimate Std. Error (Intercept) 17.49 0-48 mile 9 0.17 0.02 You are also told the following: 1" 20. -5\"): = 115.7 . 2(5). y)2 = 121.3 i=1 A.
